The water employed for flushing and cleansing the structure is to beunder a state of pressure and it is supplied from any suitable source bya pump, not shown, which may be manually operated or operated from anelectrical motor or internal combustion engine. The pump is tocommunicate with a feed pipe line 9 which is an- 5 chored to and opensinto the closet structure generally indicated at ID.

The structure H3 includes a bowl or upper section II and a discharge orbase section l2 arranged in superposed relation. The bowl sec- 20 tionconsists of a flared intermediate portion l3, an upper portion M of anysuitable contour in plan and an annular lower portion l5. The portion Mconstitutes a rim which is of greater thickness than the portion 13. Theportion l4 over- 25 hangs the inner face of portion I3 and is formedwith an endless flushing water conducting channel 16. The portion I4 isalso provided with depending spaced sidewise aligned discharge ports llleading from the bottom of channel it and opening at the top of portionl3. The portion M at its rear is also formed with a horizontallydisposed opening l8 having its wall of two different inner diameters,separated by a shoulder 19. The portion of largest inner diameter of thewall of opening I8 is threaded and arranged outwardly with respect tothe other portion of the wall. Mounted in the opening l8, abutting theshoulder l9'and the outer side of portion M, opening into the channel 56and threadedly engaging with the threads of the portion of largestdiameter of the opening it? is a flushing water intake element 23 havingattached to its outer end a depending elbow coupling 2|. The upper endof part i3 merges into the outer side of the bottom of the part M. Theupper end of portion !5 of section ll merges into the lower end ofportion Id. The inner diameter of the portion I5 gradually increasesfrom the lower to the upper end of such portion. The inner face ofportion [5 forms a flush continuation of the inner face of portion I3.The outer face of portion i5 is cutout at equally spaced points, as at22 to form horizontal ledges 23. The portion I5 is provided 55 withopenings 24 which extend from the ledges 23 to the bottom of suchportion.

The base section I2 in longitudinal section is substantially of invertedT-shaped contour and is hollow. The section I2 includes a top portion 25or vertical leg and a bottom portion which extends laterally in oppositedirections with respect to the lower end of portion 25 and provides apair of oppositely extending horizontal legs 26, 26 The leg 26 is on theintake side and the leg 26*- is on the outlet side of section l2. Theportion 25 is of annular cross section and formed at its upper end withan outwardly directed annular flange 21 of a diameter corresponding tothat of the lower end of the bottom of portion [5 of section l2. Theflange 21 is provided with spaced openings 28 which align with theopenings 24 in portion l5 of section II. The portion 25 has on its outerface a pair of oppositely extending diametrically disposed flared ribs29 merging at their upper ends into the lower face of the flange 21. Theinnerdiameter of the leg 25 is uniform. The portion 26 lengthwisethereof is provided with a chamber 39 of cylindrical form for receivingflushing water under pressure. The chamber 30 is open at its outer endand has its wall 3| threaded as at 32. The wall 3| at its inner end isof conoidal contour, as at 33. The pipe line Sextends and opens intochamber 30 at its outer'end and engages with the threads 32. The leg 26is formed .With a jet opening 34 which extends from the apex of theconoidal shaped inner end of the wall 3|. The section [2 is providedwith an outlet passage 35 consisting of a vertical branch 38 formedthroughout the leg 25 and a horizontal branch 31 formed in the leg 26for a portion of the length thereof. The branch 36 at its lower endopens into the inner end of the branch 31. The latter lengthwise alignswith the chamber 30. The jet provided bythe opening 34 discharges intothe branch 37 lengthwise thereof. The leg 26 is formed with a verticalopening 38 communicating with chamber '30. Theopening 38 has its wallthreaded. Secured to the threads of the opening 38 is a flushing waterconducting line 39 which leads from the chamber 30' and is connected atits upper end, as at 40 to the elbow coupling 2|. The leg 25 is formedwith a tubular lead-01f 4| into'which the outlet end of passage 35opens.

The lead-01f 4| has its inner part 42 of greater 7 diameter than itsouter part 43 and with the latterpro'vided with internal threads. .The apart 42 of 'thelead-off is of greater diameter than and surrounds theouter end of the passage 35. The inner'part ,42 is cutout at'its top, asat 45 to providean entrance opening therefor. The

' cutout is normally closed by a removable plate 43." The inner face'ofthe part 42 at its inner end and sides has formed integral therewith-apair ofspacedendwise aligned'lugs 41 formed with aligned grooves 48which open at the. inner 'ends and tops of the lugs. These latterprovide journals and suspensio'ns for a depending piv- .otally mountedhanger arm 49 for a vertically disposed disc valve 50 arranged in thelead-oil 4| for normally closing the outlet end of passage 30. The arm49 consists of a curved upper part 5| and an apertured lower part 52.The latter is secured by the holdfast means 53 to the valve 50. Theupper end of part 5i carries a pair of oppositely extending pintles 54which are mounted in the grooves 48. The plate 45 permits of mountingthe valve and its hanger arm within the lead-off 4|. Integral with thelower faces of the intake and outlet sides of the base section l2 arethe foot pieces 55, 56 which are disposed at right angles and extendlaterally in opposite directions with respect to said sides. The ends ofthe foot pieces are notched for the passage of holdfast means, not shownfor anchoring the structure It] upon the floor or a support.

Interposed between the bottom of portion [5 of section II and the flange2! is a washer 5?. Extending through the aligned openings 24, 28 andthrough the washer 5'! are holdfast means 58 for anchoring the sectionsll, l2 together in superposed relation. 7

When the flushing water is suppliedto. the toilet structure,simultaneously with the flushing action, the jet is formed and acts inconnection with that part of the water supplied to the bowl for openingthe outlet valve and to'force the contents of the bowl into the lead-off4|..

What I claim is: v

i. In a marine toilet structure, a top section having its upper portionin the form of a bowl formed of a vertical leg, a horizontal intake leg,

and a horizontal outlet leg, said horizontal legs merging at their innerends into the lower end of the vertical leg, said intake leg beingprovided with a chamber for receiving flushing water under compression,the body of said intake leg being formed with means at its inner end toprovide a jet opening leading from the inner end of said chamber andopening into the inner end of the horizontal outlet leg, a pivotallysuspended valve exteriorly of and for normally closing the discharge endof said outlet leg, and a flushing water conducting line leading fromsaid chamber to the water discharging means in said upper portion, thesaid jet opening disposed in alignment with the axis of said valve whenthe latter is in closing position relative tothe discharge end of saidoutlet.

2. A marine toilet including an upright bow/1,

tended to form a hollow outlet passage, a verti-.

cally disposed outwardly swinging valve for closing said outlet, a largeinlet pipe f or conducting water under pressure situated directly facingsaid passage and valve, said pipe being constricted to form a jetproducing nozzle directed im- 7 mediately against said valve to swing'itout wardly, and a tube leading from said pipe .to

flushing means near the top of the bowl.
